ME'IALLIZED PRODUCT.

Application filed November 28, 1923. Serial No. 677,386.

To all 'it may concern.'

Be it kno-wn that I, WILLIAM' F. GRUPE,

a citizen of the United States of America,

residing at Lyndhurst, county of Bergen, State of New Jersey, haveinvented certain new and useful Improvements in Metallized Products, ofwhich the following is a specification.

rlihis invention relates to improved metallic transfer media.

An object of this invention is to provide a transfer medium formetallizing purposes, either in the form of a sheet or roll, wherebyimproved metallizing effect, including depth is attained for varioustextiles, leather or like article to which .the metallic media istransferred by hot stamping, or by tipping or like procedure.

ursuant to one form of my invention,

the foil of metal or mass of comminuted metallic powder, as in the formof a layer is applied to a face of a sheetor strip of` paper or likecarrier by means of a releasable composition, and on the outer face ofthe metallic layer is applied l a layer embodying suitable sizingadmiXed with chalk or e uivalent. 4Such outer layer of the trans ermedium, it will be observed,y is disposed between the metalliclayer andthe textile or like article in the procedure of the hot st-amping, ortipping or other transfer operation, and the improved result attained bymy invention -prevents the tarnishing or darkeningof the metal and alsoeffects a depth, of the metallic layer by conjoint action of the glueand chalk constituents, or equivalent.

I have discovered that the usual textiles,I such as silk,l cloth',buckram and also leather and like materials for book cases, inner sweatsand linings for hats and the like, due to treatments with alkali, acidsor other chemicals, cause a tarnishingfor darkening of the metalliclayer due to the'transmission of such chemicals in time from thedecorated article to the metallic layer, and that the presence of thechalk'oi' like chemical, containing calcium or the equivalent,effectually prevents such transmlssion of such chemical. 'Ihe chalk orequivalent, by reason of its disposition between the metallic layer andthe article decorated, brings about v an increased luster comparable toburnishing and the virtual effect of an increased thickness of themetallic layer.

'Ihe above results, in certain circumstances, arcfurther improved by theadmixture of metallic powder in the outer or sizing layer of thetransfer medium; also for certain pur poses', I have discovered that thelife of the metallic layer is enhanced by the use of multiple layers ofsizing, one of which, such as shellac, is applied directly to themetallic layer, and the other sizing, suchas fish glue, applied to theaforesaid shellac sizing, whereby upon application of the medium to thearticle decorated, improved adhesion is at tained between the fish glueand the article .decorated,'combined by the adhesion' of shellac orequivalent between the metallic layer znd the layer of sizing of fishglue or equivaent.

Further features of the invention will be more fully understood from thefollowing detail description and the accompanying drawings, in which-Fig. 1 is a diagrammatic viewin brokenaway perspective showing a portionof one form of transfer medium embodying my invention, and comprisinglayers respectivelyof paper, releasable composition, metallic powder andtwo layers of sizing;

Fig. 2 is a central sectional view of the transfer medium shown in Fig.1; and

Fig, 3- is a diagrammatic view, in brokenaway perspective, similar toFig. l; but indicating a medium having a layer of paper, a layer ofreleasable composition, a layer of metallic material an'd a compositelayer of sizing have metallic powder Asuspended in the sizing.

Referring to Figs. 1 and 2, the stri of .paper is indicated at l, andthe layer o releasable composition is indicated at 2. Such releasablecomposition may be formed of .r

the ingredients as set forth in U. S. Patent No. 1,444,345, entitledTransfer metallic deposits, Paul Heygel, inventor, and granted onFebruary 6th, 1923, to Peerless Roll Leaf Cmpany, Inc., assignee. Itwill be understood that other forms of releasable composition may beemployed for the purposes desired.

In the form of the invention indicated in Figs. 1 and 2, the layer 2 ofreleasable composition is preferably relatively thin,

. and an admixture of beeswax and resin or other resin is well suitedfor the purpose.

'lhe layer 3 of gold leaf or other metallic toil or the like is appliedto the outer face of the layer` 2 of releasable composition.

Exteriorly of the metallic layer 3 is applied the'layer 4 containing asuitable sizing medium such as shellac, or varnish or the equivalent,admixed with powdered chalk or like chemical composition containing limeor equivalent. Such admixture 4f may be formed by thoroughly stirringthe sizing in` alcohol or like vehicle with the desired quantity ofchalk or equivalent.

Such form of the invention is applied in the usual manner tothe articleto be ornamented, as by the use of a hot die press, such as is disclosedin the U. S. Patent ,No 1,333,168, entitled liDie press, Nelson E. Funk,inventor, and granted on March 9th, 1920, to Peerless Roll Leal'Company, assignee.

Marked improvement in the resulting metallizing ornamentation isattained by Virtue of the chalk in the sizing layer. lt will beappreciated that such admixed sizing layer, by and subsequent to thetransfer operation is disposed between the article 0rnamented and themetallic layer, and such admixed sizing layer serves as a background.for the metal and maintains its brilliancy. The lime serves further topreclude any deleterious effect on the metallic layer such as tarnishingor darkening; further, the lime serves as an opaque mass or a screen to.prevent the `color or other surface eiects ofthe decorated articlebeing transmitted through the metallic layer.

The chalk or equivalent serves also to counteract any :acid or alkali orother deterring chemical employed in the manufacture or linishing of'the leather, textile or other article decorated.

rlhe chalk serves also as an effective carrier for thel` shellac and itsaccompanying binders and in the pressure and heat sta/'ge in thetransfer operation retains the shellac and therewith the metallic layerin position, to create sharp definition at the edges Aof the impression.In certain circumstances, ,.lish glue or the like effects an improvedbond with leather, textiles and like materials. ln such circumstance itis preferable to apply a layer .5, see Figs. 1 and 2, of sizing such asfish. glue, with the employment of a suitable vehicle on the outer faceof the shellac or equivalent sizing layer of the transfer medium.

To further enhance the background effect of the chalk, or equivalent, inthe outer sizing layer, metallic, powder may be :added to the sizingadmixture. Also, metallic powder without chalk may be employed withsizing admixture.

The invention is also applicable for use Leraars with metallic leal asis generally illustrated in Figli. The paper or equivalent carrier l hasapplied on one face of the releasable composition 2 and to the outerface of the layer 2 is applied the leaf 6. @n the outer :tace of thelayer 6 is applied the sizing layer 7 which may conform to the aforesaidlayers 4 and 5, or both, as hereinabove described. rlhe 'foil 5 may beburnished it desired.

lf desired, the outermost layer embodying the binder or sizing may becolored by the use of pigments or dyes which is desirable in certaintrades to conform to the prevailing colors, as for example, red forbookcases or book binding generally, and green for tipping. The use outcolor pigment or dyes may also be had with the releasable compositionalone or in combination.

lt will be observed that the particles of chalk or like materialiadmixed with the sizin and applied to the metallic layer aredistributed in the sizing after hardening and retain their inherentproperties of sub stantial opaquenessrelative to light rays afterapplication of the heat transferring operation. During the heattransferring operation, the chalk or equivalent by reason of its lowheat co-eihcient serves to retard the heat from the heated die, thusprecluding the sizing from undue flow and thereby preventing blurring orwhat is known in the art as smudging7 of the impression.

Whereas l have described my invention by reference to specilic formsthereof, it will be understood that many changes and modifications maybe made without departing from the spirit of the invention.

I claim: l. A metallic medium com rising a car- 105 rier strip, a layerof releasab e composition on one face of said strip, a metallic layerdisposed on said layer of releasable composition and an outermost layercomprising sizing admixed with a material for increasing the. lustre ofthe metallic layer.
